JAMES T. ROBB, OF BROOKLYN, NEW YORK.

LAMP-SHADE HANGER.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed March 6, 1915. Serial N 0. 12,502.

To all whom it may concern Be it known that I, JAMES T. RoBB, a subject of the King of Great Britain, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and useful Improvements in Lamp- Shade Hangers, of which the following is a specification.

This invention relates to hangers for lamp shades, and particularly to hangers for those shades which consist of a bowl or dish, as they are called, which are hung under a suitable lamp, ordinarily by means of chains from the ceiling. These dishes are often hung by means of chains provided with hooks or fastenings at the lower ends which engage holes in the rim of the shade or which engage rings on which the rim of the shade rests. In the former type holes must be drilled in the glass, which is objectionable on account of the cost, and also because the shades are frequently broken in the drilling operation. In the latter type rings of various sizes must be provided with corresponding expense.

The object of the present invention is to provide improved means for hanging a shade, without drilling the shade, and without the use of metal rings. For this purpose I provide hanging blocks or members which are interlocked with the shade by means of a mortise and tenon connection, so con structed as to permit of quick connection and disconnection, and which will prevent accidental disconnection of the shade from the hanging devices. In the embodiment shown. the tenons are molded integrally with the shade, and the hangers have mortises in which the tenons are engaged.

The invention may be embodied in various forms.

As illustrated in the accompanying drawings-Figure 1 is a side elevation of the fixture, partly in section. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a detail in inverted plan view, showing the lug or tenon on the shade.

The shade, bowl or dish, is indicated at 6, and may be in any form or design desired. This is suspended by means of a plurality of chains 7, and at the end of each chain is a hanger block 8, preferably of ornamental design, having at the top a perforated ear 9, to receive the lower link of the chain. This block has a dove-tailed or undercut mortise or recess 10, to receive the Wedgeshaped and dove-tailed tenon 11. These tenons are molded on the exterior of the shade at or about the rim thereof. It will be noticed that the side edges of the tenon and mortise are undercut as indicated at 12, as Well as the bottom edge indicated at 13, so that an effective connection is formed.

In the use of the device, the shade is supported by slipping the tenons into the mortises from above, and the Weight of the shade then retains the same in position, but the tenons may be readily lifted out to remove the shade. This simple manner of hanging a shade is much superior to the old method, and saves the cost of drilling or of other parts, and the tenons can be readily produced on the shade at the time they are made with little or no additional cost.

I claim:

The combination of a glass shade having tenons thereon with undercut vertical sides, and hangers for the shade having mortises to receive said tenons, the lower ends of the mortises being closed and abutting against the bottom of the tenons.

In testimony whereof, I affix my signature in presence of two witnesses.
